Attendance: Ragnhild, Mathieu, Charles, Kris, Graca, Shaul
Regrets: Jacques

Notes: Shaul

• Ragnhild reports on a new set of results
  • After success with 90.91 she is working with 90.92 (SH in a follow up e-mail: how do we define success quantitatively?)
  • Slide 3: With 90.92 she is fitting 12 parameters (SH in a follow up e-mail: write a note defining parameters mathematically)
  • Slide 4(?): “high residuals”. (SH: are there higher residuals here compared to 90.91 earlier?)
    • Kris: Please improve color bars; increase font size; add units
  • Slide 6: Reconstructed AME has a lot of small scale structure. That should not be the case. Indicates that the model is not fit properly. Similar for synchrotron. Suggestive of issues at low frequencies. Or that more tweaking of parameters is required.
  • Slide 8: dust is fit very well (note: no small scale structure!)
  • Slide 9: increased chi^2 when 90.91 skies are run with 90.92 underlying model! Explanation: degeneracy between foreground components creates increased chi^2.
  • CL: 2% AME polarization is 'extreme'.
  • Kris: are we using AME temperature or just polarization? Ragnhild: just polarization.
